Question System.Threading.Tasks.Task callback not changing style on VisualElement

I show a waiting animation, log the user into their account, then hiding the waiting animation element. But it's not applying the style when the callback is coming from a Task. I am seeing "called" show up in the log though.

I would rather not queue up callbacks and send them during Update() on the FirebaseManager but I think that would work.

I tried MarkDirtyRepaint() but that didn't work.

What do I need to do to get style to apply in a callback from a Task?

Code (CSharp):

1. public class FirebaseManager : MonoBehaviour
2. {
3.     ...
4.     public void TestLogin(string email, string password, Action<bool> callback) {
5.         System.Threading.Tasks.Task.Run(() => FakeSignIn()).ContinueWith(task => {
6.             callback(false);
7.         });
8.     }
9.  
10.     void FakeSignIn() {
11.         Debug.Log("fake signed in");
12.     }
13. }

Code (CSharp):

1. public class LoginPanel : VisualElement
2. {
3.     ...
4.     void OnSubmitClick() {
5.         ShowWaitState();
6.  
7.         FirebaseManager.instance.TestLogin(email, password, (x) => HideWaitState());
8.     }
9.  
10.     void HideWaitState() {
11.         Debug.Log("called");
12.         this.Q("submit-button").SetEnabled(true);
13.         this.Q("rotate-circle-panel").style.display = DisplayStyle.None;
14.     }
15. }

 

It does work from a mousedownevent.

I am on 2021.0b10 and will try in the most up-to-date version of beta and alpha later today just to check that.

 

I've made a test project for this as it doesn't work on 2022.1.0a9 or 2021.2.0b13
Open test scene and run it. Click on the green object. It should turn red. In the heirarchy select ThreadingTest and make sure use task is enabled. Then click on the green object again. It should turn yellow and two seconds later turn red.
